Might be nearer 33mm, just done it again Cos it has fresh powder so thought best to check both ends and I reckon 33mm :daumenhoch:

it may not fit over the forks that ive not got yet so cant test it.


i think it would need more than tape.

i may have a play with it, see if it fits in any other cups which could be butchered.

i wouldnt bother normally, but its a really nicely machined stem, it looks better in the flesh.
